sorry for being unclear, i was joking with words...

what i'm looking for is exactly the behaviour i get from a stereo 
correlation meter (or the W-X one for that matter), where negative means 
out-of-phase, zero means mono and positive means stereo'ish.

my intent is to be able to tell at a glance whether a signal has lots of 
X, Y, or Z information. for instance, i would expect the Y and Z meters 
to linger around 0 for an open-air recording of a single musician at the 
same elevation as the microphone. Z would move to 1 when a plane flies 
overhead (or a subway rumbles below), and Y would indicate sounds coming 
from off the median plane.
